IMPRovl-:MENT IN MEAsuRlNe-FAuce-r's'.

Specification forming part of Letters Patent No. 171,979, dated January11, 1876; application filed October 22, 1875.

To all whom it may concern: y

Be it known that we, THOMAS W,"BLACK ERBY and GEORGE K. NOLAND, both ofStanford, in the, county of Lincoln and State of Kentucky, have inventedcertain new and useful' Improvements in Measuring-Faucets and we dohereby declare that the followingis a full, clear, and exact descriptionof the same, reference being had to the accompanying drawing, whichforms part of this specification.

This invention consists in a novel combination of measuring chambers, aninterposed valve or plug chamber having separate inlet and outletpassages, and ai hollow plug or valve divided into compartments,`forming sep arate receiving and delivering chambers, and provided,respectively, with an inlet-passage and an outlet-passage, the wholeoperating by the turning of the plug to lill and draw oi' liquid fromeither measuring-chamber, substantially as hereinafter described.

Figure l represents a longitudinal vertical section of a two-ehamberedmeasuring-faucet having Vour improvements applied, and with l -its plugor valve in a position for charging or lling the one measuringchamber;Fig. 2, a similar view, but with the plug turned to discharge the liquidfrom said ineasuringehamber. Fig. 3 is a horizontal section of the sameon the line w a'. Fig. 4. is a view, in perspective, of the plug orvalve. Fig. 5 is a horizontal section on the line y y through the valveor plug and chamber in which itworks; and Fig. 6 a horizontal section ofthe same on the line A A' are the two measuring-chambers of the faucet,of different capacities to each other,

-to provide for drawing oft' different-measured quantities of liquid,according to which of the two chambers is used. These two chambersarejoined at their one or inner end by a valve or plug chamber, B, which isprovided with two independent upper inlet-passages, a a, the onecommunicating with the one measuringchamber A, and the other with theother measuring-chamber A'.` Said plug-chamber B is also provided withtwo independent lower outlet-passages, b b, in like communication,respectively, with the two measuring'chambers A A'. l The faucet is lattached to the cask or4 .barrel by a screwthread on thel upper end of lthe plug-chamber, o r otherwise. O is the plug or valve, which mayeither be kof a conical or cylindrical construction to t the chamber .B,v

`in which it turns or works. This plug C is hollow, and divided, so asto constitute au upper receiving-chamber, E, and a loweroutletcompartment, E', the former of said chambers being open at its topto receive the liquid from the cask or barrel, and the other of suchchambers or compartments being open below to provide for the dischargeof the liquid after being measured. F is the handle by which the plug 0is turned between suitable stops,

to adjust the plug into its filling or discharging positions, asVregards either measuring chamber, or to close said chambers, asrequired.v This handle may be secured on the lower end of the plug by anut, g, having airvents or recesses on its lower face for operation inconnection with longitudinal air-vents or recesses, as shown inFig. 4,on the lower end ot' the plug, which protrudes beyond the nut, toprovide for the escape of air from the neck of a bottle or other vesselunder the course of being iilled, and the mouth of which inlet-passageto the liquid from the receiving chamber E into both measuring-chambersA A', through the passages c a, by suitably turning the plug when it isrequired to till said measuring chambers. The outlet compartment E' ofthe plug C is also provided on the opposite side of the latter with apassage, f, which, when adjusted by the turning of the plug into linewith either ofthe passages b b of the plug-chamber, forms an out-let forthe liquid from either measuring-chamber A A', respectively, into theoutlet-compartment E', and when said passage fis so adj usted, theinlet-passage d of the plug is turned out of line or range with theinlet-passage a of the same measuring-chamber A or A'.

In this way, or by these means, accordingly as the plug C is turned tothe rightor to the left, to bring the passagefin linewith eitherl whichthe passage d is arranged is an air-recess, l, in the upper portion oithe plug. This recess is of a length and arranged so that, on turningthe plug O to discharge from either measuring-chamber A Athrough itsoutlet b and plug-passagef, said recess is brought in communication withone or other of two airorices, m m, in or through the sides ofthe upp'erportion of the plug-chamber B, and so that said recess l is,furthermore, in communication with the inlet-passage a of themeasuring-chamber from which the liquid is being discharged. Thisprovides for the admission of air to the top of the liquid in' themeasuringchamber being emptied, to facilitate the expulsion of theliquid, and alike for this purpose, as Well as to facilitate the runningon of all the liquid from the measuring-chambers, it is desirable tomake said chambers (when arranged horizontally) of a tapering form,diminishing in capacity toward their outer ends.

vThe measuring-chamber A is represented as fitted with aspacing stopperor plunger, G, working Within a cylindrical sleeve extendinglongitudinally within the chamber, and open at its inner end. By movingthis stopper G vin or out, the working capacity of the measuring-chamberis increased or diminished to adjust it to any desired measurement, andthe rod ofthe stopper may be graduated to facilitate such adjustment.

-To provide for drawing 0E the liquid from the cask or other vesselwithout measuring itas, for instance, when itl is desired to empty thecask or vessel-either measuring- -chamber may be fitted with adischarge-tube in its bottom, provided with a cock to close it at othertimes, but which, when opened, and the plug C is adjusted to put itsinlet-passage d in communication with the passages a a, establishes afree outlet for the liquid from the cask or vessel.

We claim- The combination of the measurin g-chambers A A', one of whichis provided with a gradu-v ating-plunger, G, the interposedvalve-chamber B, having' passages a a and b b, and the 4valve G,provided with an inlet-passage, d, and `outlet-passage j', incommunication, respectively, with avreceiving-chamber, E, andoutlet-compartment E in said valve, substantially as described.
